MINING-MACHINE MOVING AND HOLDING DEVICE.

Specification of Letters Patent.

Patented May 16, 1916.

Application filed June 27, 1910. Serial No. 569,170.

1 o 111110710721. it may concern: v

lie it known that I, EDMUND C. MORGAN, a citizen of the United States, residing at Morgan Park, in the county of Cook and State of Illinois, have invented certain new.

and useful Improvements in Mining-Machine 'Moving and Holding Devices, of which the following is a specification.

This invention relates to moving and holding devices for mining machines and has for its primary object to provide an improved device of this character for shifting I the position ofthe machine so that after it has completed its work in one position, 'itj may be shifted toa new position under its own power.

()ne of the objects is to provide an-improved combination and arrangement of parts in a device of this character;

Another object is to provide jacks or stays of improved construction which can be efliciently employed cooperatively with other parts mounted on the machine.

Other and further objects will appear in the specification and be inore specifically pointed out in the appended claims, reference being had to the accompanying drawings exemplifying the invention; and in which- Figure 1 is a diagrammatic plan view of a mining machine provided with one embodimerit-of the device forming the subject mat- Fig. 2 1s a die-- .grammatlc elevation of the same showing ter of thisspecification.

the device in operative position to advance the machine. Fig. 3 is a detail elevation of the winding drums and connections, with means for driving the same. Fig. 4 is a side elevation of one form ofan improved strut or jack. Fig. 5 is a pl'anview of a rope clamp employed in combination with other parts of the device. Fig; 6 is a diagrammatic plan view of another embodiment of the device.

In Fig. l of the drawings, a mining machine 1 having a cutter frame 2 with mov-- able cutters 3 mounted thereon is shown in suitabI'e'gposition to begin a new cut into a bank of coal 4 shown in cross section in several of the figures.- Immediately to the a little forward of the center.

rear of the mining machine 1 is disposed a ack or strut comprising a post or other suitable compression member 5 preferably circular in cross section, said post being provided on each end with caps or sockets .6 provided with projecting lugs or ears 7.

Pivotally mounted on eachof the' ears 7 is a substantially triangular shapediblock or shoe 8 which is provided with a suitable gripping face for engaging opposite wallsof the coal pocket or gallery. Movable longitudinally of the post 5, is a ring clamp 9 provided with a clamping wrench or handle 10 whereby. said clamp may be rigidly secured-to, the (post in any desired position therealong, 'sai post being preferably disposed to extend horizontally across said gallery or room. Pivotally mounted onthe ring clamp 9 is a clevis or draw bar 11 adapted to be pivotally connected to a slotted projection or lug 12 on the rear of the mining machine 1, by a bolt 13 with a handle 14. At suitable points along the post 5 suitable guides or pulley blocks 15 are provided which are adapted to receive ropes or cables 16 and 17, said ropes being connected each end to the mining machine. For

ried by thebase member of the mining machine. Said pin 20 is preferably located at approximately the center of the machine or either side of the mining machine 1 are posts or acks each of which. as shown in Flg. 2,

Disposed at I preferably comprises the post21 with a rigidly mounted claw-foot 22 and an adjustable claw-foot 2B which may be moved endwise into engagement with the top wall of coal. Adjacent the rear end. of the mining machine 1 is mounteda motor 24 which is preferably the motor which drives themining machine. the. drive shaft of said motor being provided with a driving pinion 25 meshing with bevel gears 26 and 27 which are keyed to the shaft28. Journaled upon theshaft 28 arewinding'drums .29, 30, which are held against rotating freely on the shaft 28 by provlding the periphery of of the invention, the mining machine 1 may -be swung about bolt 13, by throwing in the clutches 37 and 38 separately or simultaneously, thereby connectingthe motor 24 into driving relation with the so' that the ropes or cables 16 and 17 are played out or taken up and cause the mining machine 1 to be moved either to one side or the other. When it is desired to move the mining machine bodily forward into a new position, the cables 16 and 17 may be arranged as shown in dotted lines in Fig. 1

ment with eyelets 41 connected with the posts 21 by bands 42.

As shown in Figs. 1 and 4, a employed for use in corners and other close quarters and is provided with stiffening flanges-44 and 45 throughout a portion of its length- The upper portion of the jack 43 is deflected laterally and threaded, said threaded portion being inserted in a threaded socket 46 pointed at its outer end 47 and jack 43 is provided with a hand wheel 48 wherebV it' may be rotated to adjust its length. The

lower end of the jack 43 is provided with a.

point 49 adapted to impinge the floor of the mine and immediately above the floor line is provided a pulley or other suitable guide 50 for a cable 51. In Fig.' 5 is shown a cable clamp which may be employed in conjunction w th any of the pulleys or guides and comprises a bifurcated arm 52 pivotally mounted on the axle 53 of the pulley. W'ith in the outer end of the fork 52 is pivotally mounted an eccentric cam 54 which may be oscillated by a handle 55 into and out of clamping engagement with the cable 51.

Referring now to Fig. 6 and to the embodiment showntherein, the mining machine is provided with winding drums indicated collectively by the reference'numeral 57 and which areof similar construction to those already described bodiment. Adjacent the rear end of the mining machine, pulleys or other suitable guides 58 and 59 are mounted, over which cables 60 and 61 pass directly to'the posts or struts 21. In this embodiment the mining machine may be swung from one side to 7 38, the strut-21 on the side drums 29 and 30,

-winding drum mechanism, and in full lines in Fig. 2, the hooks 18 of said cables being in this instance in engagein the former emsuch manner as to wind and unwind the.

cables '60 and 61. Thus if the cable 60 is wound upon one of the drums while the cable 61 is being unwound from the otherdrum,"the machine is drawn bodilytoward of the cable 60. A forward movement ofthe mining machine in this embodiment may be secured in the same manner as pointed out in connection with the other embodiment. The drums 29 and30 are made to be operable separately so that should the mining machine reach the desired position while there is any slack in one of the cables, such slack may be taken up. and the device thereby adapted tohold the machine in operating position.
